Hi @kalophain,
that looks like you haven't "Attach the controller". Try following this tutorial: https://kb.unipi.technology/en:sw:01-mervis:creating-new-project-hidden#attaching_to_the_controller
Best regards,

Hello @Martin-Freundl,
first of all, you shouldn't apply 24V to a 0-10V input. There are 12.5V transils on the input, so you probably burned it.
The voltage measurement happens between the AI input and the AGND. The AGND is not connected to any other GND. Thats why you didn't measured any voltage between AGND and 24V.

@sjp770 For sure! You still have the full access to the Linuy system and what you need is the latest development branch of evok which is under development and use a websocket connection to evok from node-red :)

Hello @giamba ,
please do a proper screenshot of whole window, so we can see the error results. There are probably different variable types, but it is impossible to tell from the cut out.
Thank you,
Martin
